CLUTCH FOR SCARF-PINS.

Specification of Letters Patent.

Fatented July 25, i916.

Application led Augu st 28, 1913. Serial No. 787,048.

To @ZZ 'whom t 'may concern Be it known that I, Ronnnr FISCHER, acitizen of the United States, and a resident of Brooklyn, in the countyof Kings and State of New York, have invented certain new and usefulImprovements in Clutches for Scart-Pins, of which the Vfollowing is aspeciiication.

This invention relates to improvements in clutches tor scarf pins of thetype illustrated in Letters Patent of the United States Numbered963,537, issued to me on the 5th day o'j July, 1910, in which acylindrical thimble is provided with a projection for tilting aperforated clutch plate carried by a frame sliding within the thimble,the said projection on the thimble being formed by indenting the thimble'from the outside.

By my present invention I provide means for tilting the device withoutstriking up the projection from the thimble or indenting it from theoutside thus distiguring the exterior appearance of the clutch, and suchtilting means will also serve to retain the frame carrying the clutchplate in proper position to be tilted. l also provide means for engagingthe clutch plate Jfrom below to move the saine back to horizontal orreleasing position when the frame carrying such plate is pulleddownwardly by the iingers of the user.

ln the accompanying drawings, in which similar reference charactersdesignate coiresponding parts throughout the several views: Figure 1 isa longitudinal section illustrated in the preferred embodiment .of myinvention, the clutch being shown'in' its normal tilted position; Fig. 2is a similar longitudinal section showing thesame gripping a pin; Fig. 3is a longitudinal section at right angles to Fig. 2; and Fig. -l is asection on the line 4 4 of Fig. 3.

Referring now to these drawings, l designates a cylindrical outerthimble preferably stamped ot sheet metal and having an insertionopening 2 for the passage of scarf pin 3. Y p

4 indicates a tilting piece U-shaped in cross-section and having'itslower end 'inclined upwardly as at a. This tilting piece is driven intothe upper end of the cylindrical thimble and is stationary with relationthereto.

5 indicates a frame which is bifurcated atk its upper end to providevertical arms 5a 5a which extend vertically and slide between thetilting piece and the inner surface of the thimble. livotally mounted inthe said frame 5 near the lowery Iend of the bifurcated portion is aclu'tcliplate (3 which is normally pressed into engagement with theinclined lower ent 4a ofv the tilting piece a by means of a coil spring7 abutting between the bii-'iircated portion of the frame and a combinedwasher and straightener S secured at the lower end of the thimble andclosing the same. The frame 5 is provided with a downwardly extendingactuating stein 5b which extends through acentral opening 8a in thecombined ywasher and straightening piece 8 and the downwardly extendingactuating stem 5b is provided at its lower end with a ball 5c adapted topermit pressure to be applied between the end of the operating stem andthe thiinblo to pull the traine downwardly so as to move the clutchplate out of engagement with the tilting piece and into horizontalposition to release the pin. When the frame is pulled down tar enoughthe tilting piece lwill engage the upper end of the straightening piece8 which will cause it to assume a horizontal position and permit theeasy withdrawal of the pin.

The arrangement above described eliminates the unsightly indentation ofthe outer cylindrical thimble, retains the inner mechanisin always inproper alineinent for actuation and compels a more positive gripping andreleasing operation of the clutch. This arrangement also permits of agreater variation in the size of the pins which may be retained withinthe clutch because the clutch plate, besides its simple tilting, slidesupwardly on thel inclined surface at the lower end oit the tilting piece4- a short distance and the center of the perforation in said clutchingplate may be slightly out of alinement with the center of the insertionopening without atlecting the actuation of the clutch under normalconditions and still making it possible to have a larger grippingaperture so as to take smaller sizes of pins without aecting itspositive "operation for other sizes. A v 1 Having described vbyinvention I claim:

l. In a pin holder the combination with a suitable thimble, of a tiltingpiece connected thereto at its upper end and provided with an inclinedportion, said tilting means being U-shaped in cross-section, a framemovable the inclined face or' said .tilting piece, a

spring for normally retaining the clutch plate in engagement With saidinclined Surface and means for permitting the movement by the user ofsuch clutch plate againstr the action of the spring.

2. The combination with a scarf pin holder, of a thimble adapted toreceive the end of the scarf pin, a tiltalole Clutch plate movablelongitudinally relative to Said Copies of this patent may bre obtainedfor ve cents each, by addressing the Commissioner of Patents,

thimlole and having a perforation to receive the pin, a separate tiltingpiece liXed Within the thimble, means for forcing the clutch platetoward said fixed tilting piece and means for permitting the user toretract the 20 l ROBERT FISCHER.
